POSIX.1e requires that chmod changes the MASK rather than the GROUP_OBJ value if the ACL is non-trivial. On Windows, especially on home machines, a standard ACL often consists of entries for the user, maybe the group, and additional entries for SYSTEM and the Administrators group. A user calling chmod on a file with bog standard Windows perms usually expects that chmod changes the GROUP_OBJ perms, but given the rules from POSIX.1e we can't do that. However, since we already treat Admins and SYSTEM special in a ACL (they are not used in MASK computations) we go a step in the Windows direction to follow user expectations. If an ACL only consists of the three POSIX permissions, plus entries for Admins and SYSTEM *only*, then we change the permissions of the GROUP_OBJ entry *and* the MASK entry. * fhandler_disk_file.cc (fhandler_disk_file::chmod): Drop unused code. Add special handling for a "standard" Windows ACL. Add comment to explain. * sec_acl.cc (get_posix_access): Allow to return "standard-ness" of an ACL to the caller. Add preceeding comment to explain a bit. * security.h (get_posix_access): Align prototype. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
